| 摘要 | PURPOSE:To obtain a sealing device excellent in selaing property and high in durability, by a method wherein a sealing liquid is charged in a liquid groove provided at an outside peripheral part of a floating roof, and a slidable member which is made of an elastic material and is slidden while being pressed against a side plate of the gas holder is placed in the liquid groove. CONSTITUTION:The floating roof 22 is moved vertically on the inside of the side plate 21 of the gas holder. The liquid groove 23 is provided at the outside periphery of the floating roof 22, and a sealing liquid which is not solidified by impurities contained in a gas is charged in the groove 23. The slidable plate 24 made of an elastic material such as a rubber is placed at a part brought into contact with the side plate 21 of the holder, and is supported by suspending by a suspender 25 exteding downwardly from a suspending member provided above the outside periphery of the roof 22. A counter lever 28 penetrating through a liquid groove plate is fitted to the back surface of the slidable plate 24, and the plate 24 is pressed against the side plate 21 by the function of a counterweight 29, thereby sealing. | ||||||
